1. 控制台→網路→網路介面→管理→Open vSwitch設定→啟動Open vSwitch(把這個選項打勾)→確定 2. 透過SSH連線，輸入"ovs-vsctl show"，會顯示目前網卡橋接狀態，第一個網卡為eth0 第二為eth1 以此類推。 3. 確定要橋接的網卡編號，輸入"ovs-vsctl del-br ovs_eth1"(eth後的數字自行更改)，將網卡從預設橋接器中移除。 4. 輸入 "ovs-vsctl add-port ovs_eth0 eth1"，將網卡橋接到某虛擬橋接器。 範例 ovs-vsctl del-br ovs_eth1 //刪除ovs_eth1橋接器 ovs-vsctl del-br ovs_eth2 //刪除ovs_eth12接器 ovs-vsctl add-port ovs_eth0 eth1 // 將eth1橋接到 ovs_eth0 ovs-vsctl add-port ovs_eth0 eth2 // 將eth2橋接到 ovs_eth0 ovs-vsctl show // 顯示橋接狀態 5. 只要關機或重新開機後Open vSwitch設定會消失，如需啟動後自動設定，可以將指令加入倒任務排程表。 控制台→任務排程表→新增→觸發任務→使用者定義指令碼 使用者帳號選root 事件選開機 任務設定→使用者定義指令碼→填入要執行的Open vSwitch指令 可以把"透過電子郵件寄送執行結果"打勾，就可以看到執行結果
